AE=any new untoward medical occurrence or worsening of a pre-existing medical condition which does not necessarily have a causal relationship with this treatment. Related AE=relationship of certain, probable, possible, or missing. SAE=any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, results in the development of drug dependency or drug abuse, is an important medical event.
Time frame: up to Week 12 for AEs; up to 30 days post-double-blind period but prior to follow-up period if any for SAEs and up to 30 days post-double-blind period for Discontinuations
